Scarsdale pot princess Andrea Sanderlin must cough up a $1 million forfeiture to the feds as part of her plea deal with prosecutors, according to a Brooklyn federal court filing.

The drug-dealing mom has drawn comparisons to the main character in the Showtime TV series “Weeds,” in which a suburban widow becomes a major ganja dealer to make ends meet for her family.

Sanderlin, 45, pleaded guilty to drug raps in October after she was busted for running a multimillion-dollar ring based at a sophisticated Queens grow house.

According to the Thursday court filing, the mother of three must come up with the dough before her upcoming sentencing or face interest on the unpaid portion and the potential confiscation of other assets.

Instead of blowing cash at luxury-car dealerships, she will make her hefty forfeiture checks payable to the “United States Treasury,” the filing states.

Sanderlin, who luxuriated in a $10,000-a-month Scarsdale mansion and once drove a Maserati, faces 10 years to life in prison but will likely get a break because of her plea bargain.

She is currently out on $500,000 bail posted by several friends and will be sentenced by Judge Brian Cogan at an undetermined date.

The weed dealer drew DEA Strikeforce attention last summer when she was linked to a massive Con Ed account at the Maspeth grow house, where lamps ran up huge bills.

Authorities followed her Mercedes SUV to the inconspicuous property, where they discovered 2,800 plants worth more than $3 million.

The divorced mom told friends she was a interior designer. A raid on her rented, 5,538-square-foot Scarsdale spread turned up pot-growing literature along with $6,000 in cash.

Sanderlin’s loyal nanny was found fleeing the home with $7,900 wrapped in rubber bands.
